Pressure-induced ferroelectric phase of LaMoN
Churen Gui, Shuai Dong
Nitride perovskites are supposed to exhibit excellent properties as oxide analogues and may even have better performance in specific fields for their more covalent characters. Howe…
Low-symmetry two-dimensional BNP and CSiS structures with high and anisotropic carrier mobilities
Shixin Song, Jie Guan, David Tománek
We study the stability and electronic structure of previously unexplored two-dimensional (2D) ternary compounds BNP and CSiS. Using density functional theory,…
Ferroic orders in two-dimensional transition/rare-earth metal halides
Ming An, Shuai Dong
Since the discovery of graphene, two-dimensional materials with atomic level thickness have rapidly grown to be a prosperous field of physical science with interdisciplinary intere…
Magnetotransport Properties of Square-Net Compounds of NbSiSb and NbGeSb Single Crystals
Lei Guo, Zhao Weiyao, Ding Ning +6
We successfully grew single crystals of Si- and Ge-square-net compounds of NbSiSb and NbGeSb whose excellent crystalline quality are verified using single-crystal x-ray diffraction…
Direct Visualization of Irreducible Ferrielectricity in Crystals
Kai Du, Lei Guo, Jin Peng +12
In solids, charge polarity can one-to-one correspond to spin polarity phenomenologically, e.g. ferroelectricity/ferromagnetism, antiferroelectricity/antiferromagnetism, and even di…
Controlling the helicity of magnetic skyrmions by electrical field in frustrated magnets
Xiaoyan Yao, Jun Chen, Shuai Dong
The skyrmions generated by frustration in centrosymmetric structures host extra internal degrees of freedom: vorticity and helicity, resulting in distinctive properties and potenti…
